H3-3D Gimbal No Response

I fried my H3-3D troubleshooting FPV wiring and the gimbal began to smoke. I sent the gimbal in to DJI and its taken quite some time. I just bought a new H3-3D so I would have an extra one. However when I plugged it in it was fairly glitchy and now it doesn't attempt to adjust. I can still hear a faint power noise inside the gimbal but I'm a bit lost at what to do. Any suggestions?

I attempted this procedure to the best of my knowledge and noticed a green flash of the LED in the gimbal for a microsecond each time i tried it while powering on the phantom. I do not recall if the gimbal showed up in the assistant software and i am unable to check because the dead gimbal is in a different location from where i am now
